| 研究実績の概要 |
The study of mitochondrial activities on additional coral species from the Shikine CO2 seep confirmed the trend observed during FY2017 and further analysis showed that species resilient to OA have the potential to allocate more energy towards skeletal growth compare to less resilient species. These conclusions were presented at the Japanese Coral Reef Symposium and a paper is now in preparation. In addition the effect of OA on coral larvae using microsensors from corals species from Shikine and Vulcano, Italy, showed that OA does not affect their metabolism. A transplantation of juvenile at the CO2 seep in Shikine and Vulcano is now being done. After multiple tests, data is being acquired on the pH micro environment of different coral morphologies to test its link with OA resilience.

2: おおむね順調に進展している
理由
The results obtained on the link between mitochondrial activities and OA resilience suggest that the hypothesis tested was correct. I am now checking if this can be true on juvenile corals in addition to adult colonies.
The system built for microsensor measurements of the pH micro-environment of different coral morphologies is working well.
|
| 今後の研究の推進方策 |
The FY2019 will be used to write the paper on mitochondria and OA resilience. Additional experiment on the resilience of juveniles will be conducted. Data on pH microenvironment will be acquired.
|
| 次年度使用額が生じた理由 |
Less microsensors were purchased during FY2018 but they will be purchased during FY2019 to continue measurements.
